the class ResponseTest method testGetHeadersOffline.

@Test
public void testGetHeadersOffline() {
    ResponseImpl resp = new ResponseImpl(new XMLHttpRequest()) {

        @Override
        protected boolean isResponseReady() {
            return true;

Example 2 with XMLHttpRequest

use of elemental2.dom.XMLHttpRequest in project gwtproject by treblereel.

the class Request method fireOnResponseReceived.

/*
   * Method called when the JavaScript XmlHttpRequest object's readyState
   * reaches 4 (LOADED).
   */

    if (xmlHttpRequest == null) {

     * JavaScript XmlHttpRequest object so we manually null out our reference to
     * the JavaScriptObject

Example 3 with XMLHttpRequest

use of elemental2.dom.XMLHttpRequest in project gwtproject by treblereel.

the class RequestBuilder method doSend.

/**

 * been set, the header "Content-Type" will be used with a value of "text/plain; charset=utf-8".
 *
 * @return a {@link Request} object that can be used to track the request
 * @throws RequestException if the call fails to initiate
 * @throws NullPointerException if request data has not been set
 * @throws NullPointerException if a request callback has not been set

            // com.google.gwt.http.client.Request, do we really need it (and equivalent) here?
            // com.google.gwt.xhr.client.XMLHttpRequest has this note:
            /*
             * NOTE: Testing discovered that for some bizarre reason, on Mozilla, the
             * JavaScript <code>XmlHttpRequest.onreadystatechange</code> handler
             * function maybe still be called after it is deleted. The theory is that the
             * callback is cached somewhere. Setting it to null or an empty function does
             * seem to work properly, though.
             *
             * On IE, setting onreadystatechange to null (as opposed to an empty function)
             * sometimes throws an exception.
             *
             * End result: *always* set onreadystatechange to an empty function (never to
             * null).
